The EL1264 digital input terminal acquires the fast binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. The EtherCAT Terminal has four channels that indicate their signal state via light emitting diodes. The signals are sampled with an adjustable integer multiple (oversampling factor: n) of the bus cycle frequency (n microcycles per bus cycle). For each bus cycle, the EtherCAT Terminal generates a set of process data that is transferred collectively during the next bus cycle. The time base of the terminal can be synchronized precisely with other EtherCAT devices via distributed clocks. This XFC procedure enables the temporal resolution of the digital input signals to be increased to n times the bus cycle time.

Special properties:

• suitable for particularly fast signals due to very low input delay
• synchronized operation possible thanks to distributed clocks XFC technology
• multiple sampling of a process data through oversampling
